Abstract

"SISTEMA DE REFRIGERAçãO". Trata-se a presente patente, de um circuito de refrigerante (10) é formado ao se conectar, na ordem fornecida, um compressor (11), uma válvula seletora de quatro vias (12), um dissipador de calor externo (13), uma válvula de expansão (14), e um dissipador de calor interno (15) por um cano lateral para gases (31) e um cano lateral para líquidos (32). O circuito de refrigerante (10) é carregado com um refrigerante simples de R32 ou com um refrigerante misto de R32/Rl25 cujo teor de R32 não é menor do que 75% em peso. Como um material isolante de um motor elétrico do compressor (11), um material de resina é utilizado, e como um óleo de refrigeração é utilizado um óleo sintético. Quando a capacidade estimada de refrigeração não for superior a 5 kW, o cano lateral para líquidos (32) é formado pelo uso de um cano cujo diâmetro interno é menor do que 4,75 mm.
